Option should be allowed as a top level noun

[Nokel81]

I have something similar to the following in a .proto file:

option (grpc.gateway.protoc_gen_swagger.options.openapiv2_swagger) = {
  ...
};

This is at the "top level" (ie, not in a service or rpc block) but this does labels it an error. However, if I compile the proto file into .go code and a swagger definition it does not fail.

Currently, options are reformatted this way:

option(grpc.gateway.protoc_gen_swagger.options.openapiv2_swagger) = {
  ...
};

NOTE missing space option( this compiles just fine!

Although this is wrecking highlighting in subsequent RPC methods.
